#TURNING A 2008 MAC PRO INTO A 2018 MAC PRO FULL#
Therefore you can get either a SonnetTech card or a CalDigit card both of which have full Mac compatibility or risk a cheaper generic card. As you only mention using a USB audio interface this will not be applicable anyway.
(As per the comment by dot.com)Īll I repeat all USB3 cards have issues with external hard drives when the Mac wakes from sleep, in fact even built-in USB ports have such issues so I would not worry too much about this since there is nothing you can do about it. SonnetTech have two versions of their USB3 card, one with a shared bus for all four ports, and a more expensive one with four separate buses one per port with this therefore being able to run all four ports simultaneously at full speed. I personally wanted to avoid any possibility of such issues and therefore bought a SonnetTech card which specifically states it is compatible with Yosemite, El Capitan and Sierra. See power-connection.htmlĭespite the above official warning a lot of people have used it with no issues, I have seen some suggestions that it might be affected by being put in certain slots. The Inateck one on their own website specifically says it is not compatible with Yosemite or later.

Historically most USB3 cards even generic cheap PC ones worked fine in a classic Mac Pro with no drivers, however from Yosemite onwards and especially so for El Capitan more of these cheap generic cards have had issues. Depending on your application can be a big difference.
So imagine 4 USB 3 drives running at 5Gbps or 4 USB 3 drives sharing one 5 Gbps connection. The net result is that the better cards with multiple clocks can run all ports at the full USB 3 speed and the cards that share a clock are limited to sharing that available bandwidth across all ports. One note, the very expensive USB 3 cards tend to be more higher performance as they have independent clocks for each port, rather than one clock for all ports. Have seen some that only work on pre-Yosemite and some that only work Yosemite and newer, so do a bit of research on which ever one you are thinking about. One thing to double check on any USB 3 PCI card is what version of OS X it supports. Have had no drive corruptions issues yet, but still this is not a good message to get on your Time Machine backup disk. Then get an error about the drive not correctly dismounted. I would not recommend the Inateck KT4006 card - it seems to have a problem when the system spins down a drive due to not being used for a while.
